Which of the following is a method of creative thinking?

Mind mapping is indeed a method of creative thinking because it visually organizes information, helping to generate and structure ideas. This technique allows individuals to explore relationships between concepts and enhance their creativity by representing thoughts in a graphical format. By visually mapping out ideas, one can see connections and associations that may not be immediately evident through linear thinking. This fosters a more holistic approach to idea generation and problem-solving, encouraging free flow of thoughts without the constraints of traditional note-taking or outlining techniques.

The other options primarily involve processes that are more analytical or represent different aspects of design and evaluation. For instance, converging ideas refers to focusing on a single approach or solution from a range of possibilities, which can be more about refining than generating. Quantitative analysis involves using numerical data to inform decisions, which is typically used in evaluating outcomes rather than fostering creativity. Testing samples is a critical part of validating designs and materials but does not necessarily encourage creative thought in the initial stages of product design.
